The term Stage After Larva is PUPA, which is a four letter word. PUPA is the stage of an insect's life cycle that follows the larval stage and precedes the adult stage. During this stage, the insect undergoes a dramatic transformation, known as metamorphosis, in which its body changes shape and structure. During pupation, the insect's body becomes encased in a protective covering, such as a cocoon or chrysalis, and the insect remains inactive until it emerges as an adult.
